About 1764-RTC

The 1764-RTC is a Real-Time Clock module for establishing accurate time and date reference of a MicroLogix system. The Real-Time Clock generates a function file in the controller that can be accessed in the RSLogix500 software. This function file contains Year with range from 1998 to 2097, Month from 1-12, Day from 1-31, Hour from 0-23 following military time, Minute from 0-59, Seconds from 0-59, Day of Week from 0-6 (Saturday to Sunday), Disabled (DS) from 0 to 1 and Battery Low from 0 to 1. Real-time clock accuracy is dependent on the stability of the quartz crystal used over the operating temperature. For Temperature range 0°C (+32°F), the accuracy is +34 to -70 seconds/month. For +25°C (+77°F), +36 to -68 seconds/month. For +40°C (+104°F), +29 to -75 seconds/month and +55°C (+131°F), -133 to -237 seconds/month. Set the Real-Time Clock to synchronize with the workstation time using the RSLogix500. Click on Set Date & Time in the RTC Function File screen to set the RTC time to the current time on your PC. The RTC support removal under power. When doing so, the component will require a power cycle for the controller to recognize the component again. Practice caution in this step as the power cycle itself may require process stoppage. The Real-Time clock can be disabled from the programming software. Battery drain is reduced when clock is disabled. The RTC clock has a battery that is not replaceable. The RTC function file has an internal status bit BL (RTC:0/BL). When battery is low, the bit is set. From the first time the bit is set, it will take 14 days for the battery to completely discharge.
